so I take it you use the dooble-boiler method to reduce the extraction temperature.
simmer your trim on low with a cover is only a few degrees higher and much easier than the double-boiler (you don't have to top with water)
method and a crock-pot is very easy to do while at work. I like 24 hours of simmer time. Remember the graph for conversion of THC-acid to THC is time & temperature.
So 24 hours cook time gives a good amount of conversion (may be over-kill) Instead of the ricer they make stronger fruit presses but they run around $100. I simmer the leaf a second time in fresh water to remove more butter. I seem to loose too much butter. I just used 2 sticks but only got back one stick when all done. That's 50% loss of the butter and THC I expect.

yah the smell can be real strong and in winter it's tough to open the windows but trim is a stinky cook. this method should help with the closed top but a stove-top simmer is stinky, almost gagging.

A problem with confectionery is the high temperatures that one needs to bring the sugar to before it is at the correct stage for making candy. Typically, caramels will be brought to 245 degrees F, and if there is any plant material or even excess chlorophyll in the butter, it will have a scorched and very unpleasant flavor. So this is a little tutorial on the process by which I make my Rating: 5
